GOVERNOR.

Specification of Letters Patent. Patented D131'. 23, 1920.

Application filed August 27, 1919. Serial No. 320,296.

To all Lo/wm may concern:

Be it known that I, STANLEY M. KENER- soN, a citizen of the United States, and a resident of South Braintree, in the county of Norfolk and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Governors, of which the following is a full, clear, and exact specification.

The purpose of this invention isthe construction. of a governing device for motive powers, especially for spring impelled mechanisms, such as telephone calls, talking machines and the like, the improvements relating particularly to means for enabling the device to be made diminutive in size, simple in construction and accurate in its controlling function.

In the drawings forming part of this specification, Figure 1 is an elevation of a governor embodying my improvements. Fig. 2 is a central sectional elevation of the same. Fig. 3 is a perspective viewl of the movable friction device and allied parts. Fig. 4 is a perspective View of one of the centrifugally acting elements. Fig. 5 is a horizontal section on the line 5 5 in Fig. 1.

The govern-or spindle l receives its motion through a pinion 2 meshing with a gear 3 from which the power comes, it being stepped at 4 in the upper end of an adjusting screw plug 5, and its upper part being rotatively supported in a bea-ring at 6 comprising part of the incasing structure.

Freely movable in the spindle 1 is a sleeve 7 having a cone 9 at its lower end and a plate at its upper end, as shown more clearly in Fig. 3. The opposite ends of the plate 10 are notched or slotted radially with respect to the spindle, as at 11, for the `free movement therein of the arms of the ceni' trifugal weights.

Spaced below the cone 9 is fixedla member 4 having a conical recess 14 fitted to coact with the cone; and spaced above the plate 10 is a second plate 15 similarly slotted, as

ward under centrifugal pressure, and thereby to depress the plate 10, the sleeve 7 and the cone 9 until the latter is made to frictionally engage the conical recess 14 and to terminate further increase in velocity on the part of the spindle 1 and the source of power connected therewith.

Light springs 23 are stretched between the plates 10 and 15 having sufficient tension normally to support the weight of the plate 10, sleeve 7 and cone 9, although they are not absolutely necessary inasmuch as the friction between the cone and recess 14 is not usually enough to interfere substantially with the speeding up of the motive power'. It is only' when the friction is to a considerable degree increased by the centrifugal action of the weighted arms 12 that further increase in speed is overcome.

As shown in Fig. 4, each finger 22 is disposed at Ione side of the spindle 1 and of its arm 12 in order to avoid interference with the spindle.

The spindle 1 is stepped in the upper end of the screw plug 5 in order that by screwing the latter up or down, the spindle and connected parts will be correspondingly adjusted. A higher altitude `of said parts causes the weighted arms 12 to be swung farther away before their fingers 22 can reach and press down upon the plate 10 and thus to engender the required speed-diminishing friction between the cone and recess. This, consequently, will permit of a higher speed, while a lowering of the spindle will cause a diminution of the speed.

What I claim is:

1. A governing device comprising a driven spindle, a screw plug supporting y\its lower end, a sleeve movable on said spindle, the sleeve having a plate at one end and a cone at its other end, the cone being adjacent the lower end of the spindle, a member having a conical recess coperating with said cone, a member fixed on said spindle above said plate, weighted arms pivotally supported by the last-named member, and fingers rigid with said arms for engagement with said plate, means being provided for causing the cone to rotate with the spindle.

2. A governing device comprising a vertical driven spindle, a sleeve movable on said spindle, the sleeve having a cone at one end and a transverse plate at its other end, said plate having a radially disposed slot in each end, a member having a conical recess coperating with said cone, a transverse plate fixed upon said spindle above the firstnamed plate, Weighted arms pivoted to the second-named plate and freely movable in said slots, each arm having an offset finger engaging the first-named plate, and yielding means normally supporting the cone out of Contact with said recess.

In testimony that I claim the foregoing 10 invention, I have hereunto set my hand this eighteenth day of August, 1919.

STANLEY M. KENERSON.
